Detailed Description
The embodiments of the present invention will be described in detail below with reference to the drawings.
As shown in fig. 1-7, 1, 11, right end face of valve body, 2, 21, left end face of valve cover, 3, left valve seat, 4, right valve seat, 5, ball valve core, 6, valve rod, 7, handle, 8, left sealing waterline, 9, right sealing waterline, 10, annular boss.
A valve seat hole structure of a ball valve is shown in figures 1-3, relates to a valve seat hole for installing a valve seat in a ball valve, and is similar to a common ball valve structure in structure, and also comprises a valve body 1, a valve cover 2, a left valve seat 3, a right valve seat 4, a ball valve core 5, a valve rod 6, a handle 7 and the like.
Wherein, the valve body 1 and the valve cover 2 are screwed and connected into a whole by screw threads according to the left and right mounting positions, so a valve seat hole is formed between the right end surface 11 of the valve body and the left end surface 21 of the valve cover; the left valve seat 3, the right valve seat 4 and the ball valve core 5 are arranged in the valve seat hole, and the handle 7 is connected with the ball valve core 5 through the valve rod 6, so that the ball valve core 5 can be driven to rotate between the left valve seat and the right valve seat in a sealing manner to open and close the ball valve.
